Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described.
Engine preheater, comprises heating piece 1, shell 2 and connection terminal, as shown in Figure 1. Shell 2 is provided with air channel, and Fig. 3 shell inner chamber is air channel, heating piece in air channel, by producing the heat air that can be heated by air channel during electric current. Shell 2 is provided with grade block 10, shelves block 10 can prevent preheater after long-time use, under electrical working time inner shrapnel loses elasticity or abnormal factors situation, the part of preheater is scattered, shelves block 10 is located at side in the relative both sides of shell inner chamber, being provided with two groups, thick about the 2-3mm of shelves block 10, width is outstanding housing 2-5mm.
Shell 2 is the material of die casting aluminium or extruded aluminium, being provided with insulation layer between heating piece 1 and shell 2, insulation layer comprises base 6, shell fragment 5 and isolator 3 three layers, and base 6 contacts with shell 2, isolator 3 contacts with heating piece, and shell fragment is located between base and ceramics insulator. The material of base is high temperature resistant stainless steel material, and for ensureing intensity and the weather resistance of ceramic plate, the material of isolator 3 is the stupalith of more than 95 porcelain, and the material of shell fragment 5 is spring stainless material.
Heating piece 1 is continuous parallel folds wave structure, and heating piece 1 material is the exothermic material of high resistivity, and the material of Chinese market is siderochrome aluminium series and nichrome series substantially; Ceramics insulator 3 is provided with the circular arc groove 11 corresponding with the crest shape of heating piece 1, and the crest location of heating piece 1 is located in circular arc groove 11. Heating piece 1 two ends are provided with the heating piece interface 12 corresponding with connection terminal.
